Krav Maga Wilmington, MA

Krav Maga Grandmaster Haim Zut observed that if you are attacked only one time in twenty years you will wish that you had twenty years of training behind you. However, there is an important caveat to this, it must be training that is realistic and has been proven time and time again to be effective, not just for the naturally skilled fighter, but for every individual. This is what makes Israeli Krav Maga the best option when looking to learn reality-based self-defense. Each year tens of thousands of new recruits are drafted into the IDF (Israeli Defense Force), and taught Krav Maga. They then are made operational with many of them having to “test” their combat skills in real-life encounters. If a technique/solution is proven to work over and over again, then it remains in the syllabus, if it doesn’t a new solution is developed etc. This process has been repeated year on year, since the early 1940’s, making Krav Maga the most scientifically proven self-defense system on the planet i.e., a system you can rely on for protecting yourself and others who are in your life.

At Krav Maga Yashir (located less than five miles from the center of Wilmington, Massachusetts), we teach authentic Krav Maga that comes direct from the source. Head Instructor, Gershon Ben Keren (5th Degree Black Belt), has both trained and taught in Israel, gaining many of his teaching/instructor certificates there. He has written three books (Tuttle Publishing) on Krav Maga and in 2010 was inducted into the Museum of Israeli Martial Arts in Herzliya, Israel. Our system is not one that is based on one person’s experience or ideas but rather a comprehensive approach that has been tested and proved effective in one of the toughest environments around. One where ego has no place and survival is the only goal.

Just like the IDF, our training is accessible and safe; the goal being to get untrained and possibly unfit individuals combat ready in the shortest possible time, without injury. This is why it is so important to have Krav Maga instructors who know and understand this process rather than somebody who simply “knows” Krav Maga techniques etc. In Israel, most Krav Maga instructor programs last 29 days (12-14 hours a day), with potential instructors being invited onto such courses rather than enrolling themselves on an instructor program. Unfortunately, much of what is taught as Krav Maga outside of Israel is more of a fitness workout, that resembles the “Cosher Kravi” (Combat Fitness) programs that are taught alongside Krav Maga.

Krav Maga Books By Gershon Ben Keren

Gershon Ben Keren was approached by Tuttle Publishing in 2012 to write the first full color photographed book on Krav Maga. The techniques in the book were shot at full speed with no static, still/framed shots so that the dynamic nature of real-world violence could be captured (over 15000 photographs were taken, with those that best represented the various phases of an attack being taken from them to provide a sequence that demonstrated how such techniques would be applied in action). Scenarios were also created in the types of settings where violence occurs, adding to the realism of the photo sequences.

Krav Maga Blog

Krav Maga Blog Writer Gershon Ben Keren

Gershon Ben Keren started writing his Krav Maga Blog in 2012. It was originally designed to provide resources for the students at his schools in Massachusetts, however it soon became a much bigger proposition, educating people internationally about Krav Maga, Self-Defense and Violence. It has since been expanded to explain and put criminological theories into context, along with personal security advice gained through his work in the private security industry since 1990. Since 2012, the blog has been updated weekly, and sometimes more often depending on relevant events and incidents that have occurred that week etc. Part of the purpose of the blog is to put what may at first glance appear complex psychological and criminological concepts and ideas into an easily digestible format, alongside practical applications that they provide. The blog is fully searchable and can also be browsed by topic and subject matter.
